BCFW triangulation conjecture for amplituhedra in four dimensions
For m=4m=4m=4, let Tk,ℓ={f1,…,fN}\mathcal{T}_{k,\ell}=\{f_1,\dots,f_N\}Tk,ℓ={f1,…,fN} be the BCFW collection of positroid cells, with Tℓ,k={f1−1,…,fN−1}\mathcal{T}_{\ell,k}=\{f_1^{-1},\dots,f_N^{-1}\}Tℓ,k={f1−1,…,fN−1} up to cyclic shift. BCFW…
